How to get Subset from a Set in JavaScript ?

Answer

To get a sub Set in JavaScript, you can use Array.slice() method.



✐ Examples

1 Get Sub Set with Items

In this example,

  1. We define an array named mySet containing elements of a specific type.
  2. We specify the range of indices to extract the sub Set.
  3. We use the slice() method with the specified range to get the sub Set.

JavaScript Program

// Define array with items
const mySet = ['apple', 'banana', 'orange', 'grape', 'melon'];

// Get sub Set with items
const subSet = mySet.slice(1, 4);
console.log('Sub Set with items:', subSet);

Output

Sub Set with items: [ 'banana', 'orange', 'grape' ]

2 Get Sub Set from Empty Set

In this example,

  1. We define an empty array named mySet.
  2. We attempt to get a sub Set from the empty array, which results in an empty sub Set.

JavaScript Program

// Define empty array
const mySet = [];

// Get sub Set from empty array
const subSet = mySet.slice(1, 4);
console.log('Sub Set from empty array:', subSet);

Output

Sub Set from empty array: []
